Explain how cell membrane maintains fluid nature of cell membrane in different temperatures??

The use of renewable energy sources is a promising solution to slowing down or reversing the amount of carbon that humans release into the atmosphere. By transitioning to cleaner forms of energy, we can reduce our carbon footprint and mitigate the negative impacts of climate change.

There are several possible solutions to slowing down or reversing the amount of carbon that humans release into the atmosphere. One possible solution is the use of renewable energy sources such as solar, wind, and hydroelectric power.

By using renewable energy sources instead of fossil fuels, we can reduce the amount of carbon dioxide that is released into the atmosphere during energy production.

This is because renewable energy sources do not produce greenhouse gases like fossil fuels do. For example, when we burn coal or oil to produce electricity, we release large amounts of carbon dioxide into the atmosphere. But when we use solar panels or wind turbines to generate electricity, we do not release any carbon dioxide.

In addition to reducing carbon emissions, renewable energy sources also have other environmental benefits. For example, they do not produce air pollution like fossil fuels do, which can improve air quality and reduce the negative health impacts associated with air pollution.

The likely effect of human activity on the mice is that their habitat was divided by the artificially changed course of the river, and this process is known as allopatric speciation and is present in Option A.

Allopatric speciation is a type of speciation where the physical separation and lack of gene flow could lead to the evolution of two separate and distinct species, and here the construction of the dam likely led to the formation of a geographic barrier, which would have limited the movement of the mice between the two sides of the river and induced the speciation.

Hence, this process is known as allopatric speciation and is present in Option A.

Answer:

Adenine = 15%

Thymine = 15%

Cytosine = 35%

Guanine = 35%

Explanation:

In DNA, Adenine always bonds with Thymine, and Cytosine always bonds with Guanine.

Here Cytosine is 35%, so Guanine is also 35%.

Remaining is 100- (35+35) = 30%

If we divide 30% into Adenine and Thymine, it becomes - Adenine = 15% and Thymine = 15%.

D. mass and strength. Early gliders were mostly built of wood, with metal stays, fasteners, control cables. For strength, lightness, later wings made of wood, fabric were coupled with steel tubes in fabric as fuselage.

Since then, performance has been improved by using new materials including carbon fibre, fibre glass, and Kevlar. Due to its strong strength to weight ratio and capacity to provide a smooth outside surface to reduce drag, this material is still utilised today. Improved aerodynamics and retractable undercarriages have also reduced drag. Some gliders have wings with flaps attached to the trailing edges to maximise lift and drag at a variety of speeds.

Explanation:

In the context of "My Planet" as the selected area, here are three different factors, actions, or specific human activities that contribute to the negative environmental impact:

1. Deforestation: The clearing of forests for various purposes, such as agriculture, logging, and urbanization, has a significant negative environmental impact. Deforestation contributes to habitat loss, biodiversity depletion, soil erosion, and carbon emissions, which exacerbate climate change.

2. Pollution and waste: Human activities that result in pollution and waste generation have detrimental effects on the environment. This includes air pollution from industrial emissions and vehicle exhaust, water pollution from industrial and agricultural runoff, and improper disposal of waste materials. Pollution and waste can harm ecosystems, contaminate water sources, endanger wildlife, and contribute to climate change.

3. Overconsumption and resource depletion: Unsustainable patterns of consumption, driven by excessive demand for goods and resources, have a negative environmental impact. Overconsumption leads to the extraction of finite resources beyond sustainable levels, such as minerals, fossil fuels, and freshwater. It also contributes to the generation of waste, energy consumption, and greenhouse gas emissions associated with the production, transportation, and disposal of goods.

These factors and actions collectively contribute to the degradation of ecosystems, loss of biodiversity, climate change, and other environmental challenges that can negatively impact "My Planet." It is crucial to address these issues through sustainable practices, conservation efforts, and responsible consumption to protect and preserve the environment for future generations.
